They are just puristic and code everything we don't actually know as "?".
After all, no *T. rex* eggs are known. Look at my matrix -- some "-" there
are rather idiotic, but it's better that way, and after all many aren't
nearly that certain. They could of course have used phylogenetic bracketing
to show that *T. rex* must have had amniotic eggs, but I think taking taste
is more fun... :-)

The site is the best (if not only) introduction to cladistics of that length
that I've ever seen, and it's better than many longer, more detailed ones.
